Original ire-1,337,576, dated Aprilf20, 1920, Serial No. 27 ,612, filed ma 24,1919. Application i forreissue filed may '15, I

citizen of the United ,States, residin at Chicago, in thecounty of Cook and tate' of Illinois, have invented new and useful Improvements in Radiators, of which the following isa specification. v I i This invention relates to radiators for automobiles and. the like, and the principal object ofthe invention is to provide means. a for receiving-theoverflow caused by'the expansion ofthe water in the radiator and returning it to the radlatorwhen' the same needs refilling.

, Another object of theinvention is-to providemeans for automatically returning the collected waterto the radiator when the water therein falls below a certain point. I

.Still anotherob ject of'the invention is to provide means g for. producing a partial vacuum in the radiator by connecting the same to the suctionpart of the motor, suchl means beinguassociated with .means. for breaking the connection when the radiator is full.

Still another object of the inventionis to provide means for supplying moist vapor to the intake manifold of the motor to im-' prove the combustible quality of the motor fuel and, toeIiminate. the formation carbonin the cylinders of the motor. a

fStill another object of the invention is f to provide afloat means positioned within j or adjacent the radiator for-automatically controlling the level of the cooling medium within the radiator, and also for controlling the amount of moist vapor supplied to the intake manifold.

j 5 @The invention also consistsin certain" other features of construction and in the combinationand arranigementof the several parts, to be hereina In describing my invention in detail, ref

" erence will be had to the accompanying drawings wherein like characters denote like I ter fully described, illustrated in the accompanying drawings and specifically-pointedout in the appended claims. a i

1920. Serial No. 381,749.

Figure 1 is sectional view of -ithe front part of an automobile supplied withmy in- .to connect it with the lower part of the ra- 1 diator, as shown in the drawings. Thistank 3 receives the lower end of the usual overflow. pipe 4, the upper end of which extends into the filling spout 5-of the-radiator; The tank 3 maybe provided'with a filling spout. 6.

" Both of these spouts must be provided with caps and that for spout 5 must make. an airtight fit, so asto prevent any entrance of 'airto the radiator. The cap for spoutfi is provided with an air hole. "In the upper part-of the radiator is-located a float cham-:

her 7 the walls ojf'which are perforated to permit the free 1 entrance of water thereto. The upper end of'thisjchamber is provided with aport-S, which communicates with a pipe 9,- which: is connected with the inlet manifold of the motor. This port is con trolled by .a valve 10, located inflthe float chamber and said valve is connected with the float 11 by the rod .12.- ;It will thus be seen that when the water in thefradiator is high-enough to raise the float, theivalve will cover the portand'thus prevent the air fromlbeing exhausted from the top oftne radiator by thesuct ion action of the engine. a

A check valve 13 is located in; the pipe 9, so as to prevent any vacuum existing in the radiator from being broken by: the flow of the engine is not running.

air from the engine to the radiator, when .While the air is being exhausted am the radiator by'the. suction or partial vacuum formed in the; intake manifold the hot moist air or vapor in the upper portion of the radiator will be drawn into the'iintake manifold and mixed with the incomingfuel of the engine, and will heat and dampen the same and render it more combustible. and less liable to the formation of carbon.

When the system is filled with water and the engine started, the water will expand on being heated, so that it will rise above the overflow pipeand the water passing through this pipe will pass into the tank 3. When the water level drops inthe radiator for any reason low enough to permit the valve to uncover the port 8, a vacuum will be created in the upper part of the radiator by the suction of the engine, so that the watenin the tank 3 will be drawn through the pipe 4 back into the radiator and at the same time moist air or vapor in the upper portion of the radiator is drawn into the intake manifold and mixed with the gases and will heat and moisten the same, and this will continue until the water reaches the float 11 and raises the same to cause the valve 10 to cover the port 8, and thus prevent further exhausting of the air from the radlator. I

' As there is always moreo'r lessvibration while the engine is running the valve will also be vibrated and slightly opened and permit a small constant supply of moist vapor to the intake manifold.

-"-In this way, the radiator is automatically kept filled, and when an anti-freezing s'olntion, is, used in the radiator there is nodan ger of the'same bein'g discharged through the 'overfiow pipe and lost.

' In the modification shown mIfigL 3 the;

float chamber is provided with a port 8, which opens into the pipe 9, which 15 connected with the intake manifold as before described, but the valve 10 is adapted to control a port lfl communicating with vthe upper part of the pipe 9 and opening out into a large pipe 15, which leads to the atmosphere. I raised by the water in the radiator the a r will pass from the pipe 15 into the pipe 9 and thus break the suction in the float cham her and radiator, as the port 14 ismuch larger than the port 8. i

' What I claim is:

1. A, device of. theclass described, com

prising an air-tight radiator, a tank, a pipe connecting the radiator with the tank, means for creating a vacuum in said radiator, and means for automatically breaking said vacuum when the'iwater reaches a cer tain point in the radiator. 2. A device of the class described, comprising an air-tight radiator, atank, a pipe connecting the radiator with the tank, a float chamber in said radiator; meansv for connecting the same with the inlet manifold oft he motor, a valve controlling said con nection, and a float in said chamber connected with said valve. I r

3. An engine, comprising aradiator member, a tank, an overflow means in communip'heric'pressu're to return a portion of the cooling medium within the tank In this way when the float is cation with the upper portion of the radiator member and the lower portionof the tank, and means caused by and while the engine is in operation for automaticallymoving a cooling medium contained within the tank through the overflow means and into the radiator member When the level member which will cause atmospheric pres; sure to force the cooling medlum contained within the tank through the overflow means and into the radiator member when the cooling medium within the radiator memberis lowered to a predetermined level.

5. An engine, comprising a radiator memher for containing a cooling mediumfa t'ank for containing a similar medium, anov'er flow pipe extending into theupper' portion of the radiator and into the'lower portion of the tank to'permit the cooling medium to overfiow from "the radiator through the pipe and into thetank, and the return of the cooling medium "to the radiator, another pipe extending from the radiator member to the. engine to create a condition within the radiator member .while the en'- gine is in operation whlch will cause atmosthroughthe overflow pipe and into the radiatormember when thecooling medium Within the radiator is lowered to a predeter mined level.
